Spray booths keep contaminants out of painting areas, ensuring quality and saving time and money. They are fully enclosed and pressurized, with built-in compression hoses for spray painting. Maintenance is crucial for large and small booths, and workers must wear protective gear.
A spray booth is a structure designed to keep dust and other contaminants out of the painting area. Contaminants can have a major impact on the quality of a paint job, whether the paint is applied to a piece of china or a commercial aircraft. Using paint booths ensures painting jobs are done quickly and in a clean environment, saving money and time in the long run for the company doing the job. Various companies sell spray booths for a wide variety of applications.
The basic layout of a spray booth is the same regardless of size. Paint booths are designed to be fully enclosed, with large doors to move goods in and out. The air is kept pressurized with the use of fans and compression, to ensure that the air is exhausted from the spray booth, rather than being sucked in. Most spray booths have built-in compression hoses to attach paint nozzles for spray painting. , or an operator can bring a separate compression unit.
When an operator wants to paint something, it is carefully cleaned and prepared before taking it to the paint booth. Most spray booths are designed for spray paint applications, whereby the operator sprays the object and then allows the paint to dry. Some paint booths actually bake the paint, as is the case with automotive paint jobs, since the quick bake cures the paint, making it more resistant to scratches and damage.
Some paint booths are extremely large, designed to accommodate large trucks or commercial aircraft. Keeping conditions clean in these spray booths is a lot of work, as even a small contamination load can spell a major paint job disaster. Paint booth doors are always kept closed, and paint hoses and nozzles are cleaned and replaced regularly. In addition, scrupulously clean air inlet filters are used, and the compression system is regularly checked to make sure the spray booth is running efficiently.
A smaller spray booth, such as one designed for finishing ceramics and woodworking projects, also requires maintenance work, though not on the scale of a commercial spray booth. Keeping the working environment clean is especially important for ceramics, as impurities in the glaze can cause major problems in kilns.
People who work in paint booths must also be cautious. Wearing face and eye protection along with a respirator is recommended as spray paint is unhealthy to inhale. Many companies also have special uniforms for their employees to wear in the spray booth, so they don’t introduce contaminants into the space.
